The Ducks held a single workout as the second week of preseason camp begins to draw to a close.

Venue: Outdoor practice fieldsFormat: Full padsSituations: Various down-and-distance scenarios plus an overtime drill to close the day.

Highlights: Marcus Mariota was sharp during seven-on-seven, with help from some athletic receptions by Chance Allen and Blake Stanton. To my eye, Allen has really come on in the last few days, making a case for a spot in the primary rotation. He did have at least one pass go uncaught today, when Avery Patterson was bearing down on him in 11-on-11. Discretion perhaps the better part of valor in that case. Erick Dargan did a nice job beating a John Mundt block during that same 11-on-11 session, and Mana Greig cleared a nice path for De'Anthony Thomas on the ground.

Most entertaining period: The defenses kept the offense out of the end zone on all four tries in overtime, and Dior Mathis blocked a field goal to keep the offense off the scoreboard completely on one rep. In the first situation, the offense didn't manage a first down in part due to a rare dropped pass by Thomas, who did 20 pushups as penance. That left a 35-yard field goal try for Matt Wogan, who wasn't able to convert, capping an erratic day in what has otherwise been a good week for the freshman.

Byron Marshall helped the next group get down to the 9-yard line with some strong running, and Alejandro Maldonado converted from there. Maldonado got the next try as well, and Mathis blocked the kick. The final overtime period ended with Wogan converting a 30-yard attempt. Afterward, Mark Helfrich said he blew a few plays dead perhaps prematurely, and that Mariota might have scored on a running play at one point.

Other observations: Tyrell Robinson continues to look like a guy who can help on special teams, doing some work as a blocker on kickoff return today. Helfrich said decisions will be made after next week about redshirt status, and special teams contributions will be a big factor. … Cool moment at one point during that drill when Don Pellum pulled both Tyrell Robinson and Tyree Robinson aside to go over some concepts. To play with one's twin brother has to be a thrill. … Also striking at that moment was the size difference between the brothers. I'd estimate Tyree, a defensive back, around 195 pounds right now, and Tyrell, a linebacker, closer to 215.

Up next: The Ducks were given a day off Friday by Helfrich, and will practice twice Saturday.
